Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446032, here are decompositions:

73 + 31445959 = 31446032
103 + 31445929 = 31446032
181 + 31445851 = 31446032
199 + 31445833 = 31446032
313 + 31445719 = 31446032
421 + 31445611 = 31446032
601 + 31445431 = 31446032
613 + 31445419 = 31446032

Showing the first eight; more decompositions exist.
